Effect of biochar as reductant on magnetizing-roasting ...

Abstract. The effect of biochar substituted for anthracite as reductant on magnetizing-roasting pyrite cinder was investigated. The key of magnetizing-roasting is the gasification reaction between reductants and CO 2.Since biochar could react with CO 2 more rapidly at lower temperature, the reactivity of biochar is better than that of anthracite. The gasification of biochar could produce ...
